09/00
The tekmar Room Temperature Unit (RTU) 060 onsists of a temperature sensor, adjustable dial, push but-
ton, and indi ator LED. The adjustable dial is used to set the desired indoor temperature during the o upied
period. The push button is used to provide either a temporary o upied override or a permanent uno upied
override. The indi ator LED is used to indi ate the type of override that is urrently in effe t. The RTU 060 dial
has a temperature range from 40 to 100°F (4 to 38°C). In ases where a restri ted temperature range is
required, the dial rotation an be limited using limit pins supplied with the RTU.
Note: This RTU is only ompatible with the tekmar Zone Control 369.
Installation
STEP ONE REMOVING THE RONT COVER
Pla e a s rewdriver or similar obje t into the small slot lo ated in the top of the 060. Push the
s rewdriver against the plasti tab and pull the top of the front over so that it pivots around
the bottom edge of the 060.
STEP TWO MOUNTING THE 060
The base of the 060 should be se urely installed in the desired lo ation. Mount the 060 dire tly
to the desired lo ation using two #6 - 1” s rews. The s rews are inserted through the mounting
holes and must be se urely fastened to the desired lo ation. If possible, at least one of the
s rews should enter a wall stud or similar surfa e. If the 060 is to be mounted to a 2” x 4”
ele tri al box, an Adaptor Plate 007 is required. This plate will mount to the ele tri al box and
the 060 will then mount to the plate.
STEP THREE WIRING THE 060
Run 18 AWG twisted pair or similar wire between the 060 and the ontrol. Insert the wires
through the hole provided in the ba k of the 060 en losure and onne t them to the Com and
tekmar Net™(tN1) terminals. Do not run the wires parallel to telephone or power lines as this
may interfere with the operation of the 060. If the 060 wires are lo ated in an area with strong
sour es of ele tromagneti noise, shielded able should be used or the wires an be run in
a grounded metal onduit.
NOTE: Do not apply power to the 060. The 060 is to be wired directly to the control. The
connection between the control and the 060 is polarity sensitive. The Com terminal of
the 060 must be connected to the appropriate terminal of the control. f the wires are
reversed, the 060 will not function and the control will display an error message.
STEP OUR INSTALLING THE RONT COVER
Align the hinges on the bottom of the front over with the bottom of the 060 mounting base.
Pivot the front over around the bottom hinges and push the top against the mounting base
until it snaps firmly into pla e.
Settings
To set a desired temperature, turn the RTU dial until the temperature is seen in the display window.
Temperature Scale
The RTU is supplied with two temperature s ales. The RTU omes with the °F s ale
displayed in the window. The °C temperature s ale is lo ated on the ba k of the °F. In order
to hange the s ale to °C, remove the front over, lift and pull the s ale off the dial, flip it over
and repla e it.
Limiting the Temperature Range
The temperature range on the 060 an be limited in order to avoid extreme temperature
settings or any tampering with the setting.
• Turn the dial until the desired temperature is at the bottom of the 060.
• Remove the front over by following Step One of the Installation pro edure.
• Lift and pull the s ale off the dial. Be areful not to turn the dial while removing the s ale. With the s ale off, a series of small holes
will be visible around the dial. Behind the dial there is a post whi h an be used to limit the rotation of the dial. Two aluminum limit
pins are provided in the dial.

position as the ounter- lo kwise rotation is now restri ted by the pin.
Setting a Maximum Temperature Limit
Insert one of the pins into the hole that is slightly to the right of the post.
Setting a ixed Temperature
Insert one of the pins into the hole in the bottom of the dial su h that the pin enters the post behind
the dial. With the pin in pla e the dial should be fixed in position.
